簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7 - 8; 臀鰭軟條: 8. Pink-white. No eyes (vestigial eye tissues under skin). No pelvic fins. Usually 8 anal rays; 9-11 branched caudal rays.
粉紅的-白色。 沒有眼 (在皮膚下面的退化眼組織). 沒有腹鰭。 通常 8個臀鰭鰭條; 9-11 分枝了尾部的鰭條。
Adults inhabit subterranean waters of quite small cave streams. Preferred habitat in these caves is chert rubble though individuals are also found in areas of silt-sand substrates. Stomachs examined contained copepods which constituted about 70-90% by volume with the balance being primarily small salamanders, crayfish, isopods, amphipods and young of their own species (Ref. 34868). Eggs are carried in gill chambers of females (Ref. 205). Threatened by overfishing (Ref. 10172).
棲息於相當小洞穴溪流的地下水域。 雖然它也被發現於淤泥-沙子底部的區域，在這些洞穴的它的優先棲息地是黑矽石碎石。 腹部檢查後發現有了構成大約體積的 70-90% 的橈腳類的動物其餘主要是小的蠑螈，小龍蝦，等足目動物，片腳類動物與同種的幼魚.(參考文獻 34868) 受到威脅的由於捕撈過度。 (參考文獻 10172)
